Bash on Windows.

Yes, it's true; some say hell has frozen over, but it will be possible to use Bash on Windows. This is not about a virtual machine solution like VirtualBox. File systems will be shared, so Linux enthusiasts won't have to rewrite any scripts; they should work the same way for files located on an NTFS partition. Commands like "cpuinfo" also work (as shown in the material below), where the output provides information about the actual computer rather than the virtualizer. Most of the interesting information about Bash on Windows can be found in the materials below, which were published on channel9.msdn.com.

The fact that "Linux on Windows" is no joke is further evidenced by Microsoft hiring the head of Linux from Oracle, known as "Mr. Linux," as reported by zdnet.
